To the Board of Directors, Management and Stakeholders of Boral Limited:

Boral Limited (Boral) commissioned Net Balance Management Group Pty Ltd (Net Balance) to provide independent assurance of its 2009 Sustainability Report (the 'report'). The report presents Boral's sustainability performance over the period 1 July 2008 to 30 June 2009. Boral was responsible for the preparation of the report and this statement represents the assurance provider's independent opinion. Net Balance's responsibility in performing its assurance activities is to the Board and Management of Boral alone and in accordance with the terms of reference agreed with them. Other stakeholders should perform their own due diligence before taking any action as a result of this statement.

Assurance Standard and Objectives
The assurance was undertaken in accordance with the AA1000 2008 Assurance Standard (AA1000AS). Assurance undertaken using this standard provides a comprehensive way of ensuring that an organisation is responsible for its management, performance and reporting on sustainability issues. This is achieved through the evaluation of the organisation's adherence to the AA1000 Accountability Principles (2008) and by reviewing the accuracy and quality of disclosed sustainability performance information.
The AA1000 Accountability Principles (2008) against which Boral's processes are assessed include:

  • Inclusivity: An assessment is made on whether the organisation has included stakeholders in developing and achieving an accountable and strategic response to sustainability.
  • Materiality: An assessment is made on whether the organisation has included in its report the material information required by its stakeholders to be able to make informed judgements, decisions and actions.
  • Responsiveness: An assessment is made on whether the organisation has responded to stakeholder concerns, policies and relevant standards and adequately communicated these in its report.

Assurance Type, Level and Methodology
Net Balance provided Type 2 moderate level of assurance in accordance with the AA1000AS (2008). This involved an assessment of the organisation's adherence to the AA1000 Accountability Principles (2008) and an assessment of the accuracy and quality of the sustainability performance related information contained within the report. A full description of the Assurance methodology is available at www.boral.com.au/sustainability.

Assurance Limitations
The assurance scope covered the whole report and focussed on systems and activities of Boral during the reporting period, with the following exceptions:

  • The scope of work did not involve verification of financial data, other than that relating to environmental, social or broader economic performance.
  • The assurance provider's involvement with stakeholder engagement was limited to reviewing external and internal stakeholder engagement processes and outcomes.
  • Compliance with the National Greenhouse and Energy Reporting (NGER) Act 2007 was not included in the scope of the assurance.

Our Independence and Competency
Net Balance was not responsible for preparation of any part of the report. During the reporting period, Net Balance was commissioned by Boral to undertake an independent review of divisional Boral Sustainability Diagnostic Tool (BSDT) scores. This independent review of divisional sustainability performance assisted with the objectives of the broader assurance engagement. Detailed information on Net Balance's assurance competency is available at www.boral.com.au/sustainability.

Net Balance reviewed a number of case studies from the report that highlighted engagement with internal and external stakeholders.
